\textbf{Effective Time Resolution:}\\  \textit{def. } The full-width at 10\% maximum of the polyphase filterbank impulse response.  \end{quote}  While the above requirements would appear to satisfy the needs of the pulsar community, the practicality of these requirements is seriously undermined limited  by the computational burden of performing coherent dedispersion at low frequencies on wide frequency channels. This burden only becomes more difficult to manage as we move to larger dispersion measures (DMs). As such, the requirements suggested above need a modifier that allows them to change with DM. This modifier is provided by the physical limitation that interstellar scattering places on the minimum resolvable feature width in a pulse profile. This is discussed in detail below.
